title: [A case report of thoracic outlet syndrome with acute arterial obstruction caused by abnormal first rib].
abstract: A 33-year-old male was transferred to our hospital because of coldness, numbness and pain in his right arm. Chest X-ray showed abnormal first ribs on both sides that were attached to the second ribs below the clavicles. Angiogram revealed an aneurysm of right subclavian artery, thrombus in the aneurysm and embolism to the brachial artery. Thrombectomy using a Fogarty catheter was done and the radial pulse recovered. Surgical resection of the abnormal first rib and thrombectomy was performed, because ischemic symptoms recurred in spite of anticoagulation and antiplatelet therapy. Acute arterial occlusion in patients with thoracic outlet syndrome is rare. The literature on arterial complications of thoracic outlet syndrome is reviewed.
